Mega Man X Legacy Collection is following in the footsteps of the previous Mega Man Legacy Collections, but is going a step further with the new X Challenge Mode. 
The new mode pits X in a new armor set against bosses from the series history. Rather than being a simple boss rush, however, the X Challenge mode combines Mavericks from different games and puts them into a single room with X. The bosses are arranged by themes, like ice bosses Chill Penguin and Frost Walrus together, Spiral Pegasus and Dark Necrobat to represent light and shadow, and the genuinely upsetting combination of Vile and High Max.
X only gets to choose two weapons aside from the X Buster to bring with him to the fights, which is a lot harder than it sounds. You can check out a trailer of the X Challenge fights below.
Mega Man X Legacy Collection 1 + 2 is releasing on PlayStation 4, Xbox One, PC, and Switch on July 24.
